I’m working on a custom digital signage project to be mass produce using Argon one v2 with the remote control and I was wondering how can I launch a custom command using the remote? I need an example and the location of the script listening the the IR remote signal.
I’m sort of in the same boat. I would like the power button to NOT turn on or off my RPi 4, but instead trigger a script which would ultimately turn on/off my amplifier. Note: I’m not using the RPi OS, but a PiCorePlayer install (Tiny Core Linux). None of the Argon scripts work here…

For your custom digital signage project using the Argon One V2 with the remote control, you can capture and trigger custom commands by listening for IR signals. Here’s an example of how to set it up:
1. Install Necessary Tools
First, ensure you have the required tools to receive the IR remote signals. You’ll need the lirc (Linux Infrared Remote Control) package, which allows you to control devices via IR.
Run these commands to install lirc:
bash
复制代码
sudo apt update
sudo apt install lirc
2. Configure IR Receiver
The Argon One V2 case has an integrated IR receiver, so you need to make sure it’s correctly configured. For most setups, the IR receiver should automatically be detected.
Check if the receiver is working by running:
bash
复制代码
dmesg | grep lirc
If it’s detected, you should see something like:
lirc_dev: IR remote control driver registered.
3. Configure lircd.conf
You’ll need a configuration file (lircd.conf) that maps your remote control’s buttons to commands. You can use irrecord to create this file, or if you already have a configuration file for your remote, you can use that.
If you want to record your remote’s signals, follow these steps:
bash
复制代码
irrecord ~/lircd.conf
Follow the prompts to press each button on the remote. This will create a configuration file (lircd.conf) that maps each remote button to a command.
4. Listen for IR Signals
Once the lircd.conf file is set up, start the lircd daemon, which listens for IR signals:
bash
复制代码
sudo systemctl start lircd
Then, check if the remote is triggering actions:
bash
复制代码
irw
You should see output showing which buttons are pressed (for example, KEY_PLAY or KEY_PAUSE).
5. Trigger Custom Commands
Now you can use these IR signals to trigger custom commands. For example, you could have a script that listens for a specific key press and executes a command.
Example Script to Listen for a Key Press:
Create a script like ir-remote-script.sh that listens for a key press and executes a command:
bash
复制代码
#!/bin/bash
while true; do
ir-keytable -t | grep -i 'KEY_1' && ./your-custom-command.sh
sleep 0.1
done
In this example, if the “KEY_1” button on your remote is pressed, the script runs your-custom-command.sh. You can modify the key names and commands as per your setup.
6. Create Custom Command Script
Make sure your custom script (e.g., your-custom-command.sh) is executable and performs whatever action you need, like launching a media player, showing a specific sign, etc.
bash
复制代码
chmod +x your-custom-command.sh
Example of a Simple Script:
Here’s an example where a remote button press launches a web page or a video:
bash
复制代码
#!/bin/bash
# your-custom-command.sh
# Example: Launch a specific URL for digital signage
chromium-browser --kiosk http://your-signage-url.com
7. Autostart on Boot
If you want this to start automatically when the system boots up, you can add your script to rc.local or create a systemd service.
Conclusion:
By configuring the IR receiver and using lircd to listen for specific key presses, you can trigger custom commands in your digital signage project. This gives you full control over how the remote can interact with your signage system.
